RIDGE-ROLL FINIAL.

To all whom it may concern:

Be it known that 1, MICHAEL ALBERT, a citizen of the United States, and resident of hiilwaukee, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Ridge-Roll Finials, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

This invention relates to certain new and useful improvements in metal roof caps, and refers more particularly to what may be termed a ridge roll finial.

Heretofore, such caps have been made by forming an end head section and securing it to the roll head by the aid of solder, with the consequent disadvantage that upon rough 1 handling of the structure, the solder would become loosened permitting leakage and detachmentof the spherical head. Such caps have also been made by securing the edge of the end head member with a substantially U-shaped channel formed on the adjacent roll end. This construction has also proven faulty as a tight joint is not formed thereby and consequently after handling a leakage is permitted at the-joint.

It is one object of this invention to eliminate the use of solder in a structure of this character and to provide an economical manner of connection of the head to the ridge roll by interlocking engagement of bent seam portions on the ridge roll and the head edge, to effect a permanent strong conned tion with the spherical head.

This invention has for another of its objects to provide a structure of the class described, which will be coated with a layer of metal, such as copper, tin, zinc, or any other suitable coating, whereby interlocking connections between the various parts will be made substantially solid.

It is a still further object of this invention to provide a head member for the structure above described, which is formed in two sections having improved non-detachable interlocking connection.

With the above and other objects in view which will appear as the description proceeds, my invention resides in the novel construction, combination and arrangement of parts substantially as hereinafter described and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the Specification of Letters Patent. Patgnited Rig-y 2 -1922; Application filed September 16, 1920. seria 'no. 410,715.

herein disclosed invention may be madeas come within the scope of the claims.

In the accompanying drawing, I have illustrated one complete example ofv the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application of the principles thereof, and in which:

Figure 1 is'a side elevation view of a roofing cap structure embodying my invention, portionsof the cap being broken away to more clearly show' the seam structure, and the'outer layerfof metallic covering being shownin section; v

Figure 2 is a view part in section and part in elevation taken on the plane of line 22 of Figure'l; and

Figure 8 is a fragmentary perspective view of a portion of the ridge roll adjacent the head member.

Referring now more particularly to the accompanying drawing, there is provided a usual ridge roll plate having its intermediate portion longitudinally curved ina major are toform the roll 5 and having its sides divergently extended, as at 6, to seat. on the ridge of a roof and preferably. provided with outer shoulder portions 7 The outer end of the roll lies preferably in an oblique plane for connection with an end of a head member, which, in the present instant, comprises an outer hemispherical section 8, and an inner truncated spherical section 9,'said sections being connected by an improved form of seam.

r The seam connection between the two sec tions of the head member is formed by providing the edge of one section with in wardly and then outwardly bent rib 10 to provide a channel in which is sprung the inturned edge 11 of the other section. This construction forms a non-detachable rigid connection between the sections, as will be readily obvious.

The end member thus formed is provided with a rigid connection with the ridge'roll by curling or inturning the edge 12 thereof to form a head and engaging the same over the adjacent end of the roll which is then turned laterally and then inwardly, as at 13, to provide a rigid interlocking connection, as clearly shown in Figure 1. This construction forms a smooth rigid joint between the two parts which requires no solder, presents a pleasing appearance, and;

which necessitates the use of a minimum amount of coating material, as will presently appear. The end portions of the roll sides, adjacent the head, are bent inwardly, as at 14, and the upper ends of these bent portions carry tongues 15, which project upwardly into the head member. As depicted in Figures 1 and 2 the sides 6 extend slightly beyond the adjacent roll end to provide a shoulder, which shoulder passes into an incut portion or recess l6-of the end member, see Figures 1 and 2. This construction permits the tongues 15 to project into the interior of the head member, engaging the edges of the recess 16, thereby looking the two parts against relative rotary movement'and further insuring against the breaking of the coatlng materlal.

An exceedingly simple and strong metal roofing cap is thus provided wherein the necessity of using solder as a connecting means is entirely avoided,thus enabling the cap to successfully withstand relatively greater stresses incidental to their manipulation than the common types of caps. While the structure so far described is sufiicient in itself, the entire cap may be, if desired, galvanized or coated with any substance or metal, as at 17, whereby the various seams will be filled in and made solid. This step insures an absolute waterproof joint and presents a smooth unbroken surface, as will be readily apparent.

. While this invention has been shown and described as associated with a roof cap having a spherical head portion, it will be appreciated that the same is equally applicable to roofing caps of various shapes, and hence,

the term spherical as used-throughout the specification and claims may be taken to mean any shape for association with the ridge roll.

\Vhat I claim as my invention is:

'1. A device of the class described comprising a head member provided with an opening the edges of which are turned over to form a bead; and a roll portion having an end engaging said opening and flared outwardly to intimately contact with said head whereby a smooth rigid joint is obtainedbetween the'two members. r

2. A device of the class described com prising a head member provided with a sub st'antially circular opening, a portion of the edge of which is cut away to form a recess; and a roll portion engaging said opening and provided with a tongue adapted to enter said recess to lock the parts against relative rotary movement.

3. A device of the class described comprising a head member provided withasubstantially circular opening a portion of the edge of which is cut away to form a recess, the remaining portions of said edge being inturned to form a bead; and a roll portion havlng an end engaging said'open-l ing and flared outwardly to intlmately contact with said bead, said roll portion being also provided with a plurality of tongues. adapted to enter said recess and engage the sides thereof to lock the parts together against relative rotary movement. f

In testimony whereof, I afiix my signa:

ture.
